1. Keep networking

Whether you're working, retired or thinking about reentering the job force, networking is essential. Engaging with people on Facebook, Twitter, LinkedIn and face-to-face in industry groups will keep you current and connected. Keep your résumé up to date, too.

2. Build a personal board of directors

Life after 50 is filled with change and can be confusing. Whether you're looking to switch careers, pursue a relationship (or end one) or buy a house, having a trusted posse to review life's bigger questions helps. Invite several nonjudgmental friends who will encourage and guide you. And do the same for them.

3. Don't smoke

This is a no-brainer, but it's shocking that we still see smokers on the street. Smoking is the leading cause of preventable disease and death, according to the American Lung Association. If you're over 50 and still smoking, get help to quit.

4. Have safe sex

Don't think because you are over 50 you are immune to sexually transmitted disease. You are not. Make sure you know the scoop on your partner before you proceed, even if you're in a steady relationship. Use condoms. Discuss your risk factors with your doctor and get tested for the most common STDs, especially when you start a relationship. Insist that your partner do the same.
